TXM30M0004322DBCDO00T 产品概述

一、产品概况

TXM30M0004322DBCDO00T是雅晶鑫(YJX)推出的一款国产贴片晶振,基频30.000MHz,采用SMD3225-4P封装,外形尺寸3.2×2.5mm,面向对频率精度和稳定性有中高要求的通信、时钟及射频前端等电子设备。器件支持常温工作条件下的高精度定频输出,适合贴片回流焊工艺的大批量生产。

二、主要技术参数

  • 晶振类型:贴片晶振(SMD)
  • 标称频率:30.000 MHz
  • 常温频差:±10 ppm(25℃)
  • 频率稳定度(温度影响等综合):±20 ppm
  • 负载电容:10 pF(建议C1=C2=10 pF)
  • 等效串联电阻(ESR):30 Ω
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装型号:SMD3225-4P
  • 品牌:YJX(雅晶鑫),国产产地

三、关键特性

  • 高频率点:30MHz适用于高速时钟与射频系统的本振或参考源。
  • 高精度:常温频差±10ppm,保证系统在常温下的时间基准准确性。
  • 良好稳定性:总体频率稳定度±20ppm,适应宽温度范围的工业级应用。
  • 可贴片化:SMD3225封装支持自动贴片与回流焊,便于SMT生产线集成。
  • 低ESR:30Ω 的等效串联电阻有利于振荡器启动并获得可靠的振荡幅度。

四、典型应用

  • 微控制器系统时钟、主时钟源
  • 通信设备本振或参考时钟(无线收发、基带处理)
  • 数据采集与高速接口(ADC、FPGA、高速串行总线)
  • 精密定时与测量设备
  • 各类消费电子、工业控制与物联网终端

五、封装与焊接建议

  • 封装:SMD3225-4P,建议在PCB上预留与封装匹配的焊盘与焊膏量以保证焊接质量。
  • 焊接:兼容无铅回流焊工艺,建议按PCB制造商和晶振供应商的回流曲线进行温度控制,避免超过推荐焊接峰值温度和保温时间。
  • 板上布局:晶振附近避免大电流回路与强电磁干扰源,地线应良好,若为差分或单端振荡器,请参考芯片厂商的布局建议并在芯片与晶振之间保留适当距离。

六、使用注意事项与选型建议

  • 负载电容匹配:为获得标称频率,外接负载电容应采用10pF(建议左右对称),并考虑引线电容及PCB寄生电容的影响。
  • 驱动与启动:选择与晶体匹配的振荡器电路(如Pierce结构),并控制驱动功率在安全范围内,避免过驱动导致晶体损伤或频率漂移。
  • 温度与环境:在极端温度或高湿环境下,频率可能超出标称稳定度,关键应用建议做环境测评。
  • ESR与启动性:当电路对启动性能要求高时,注意ESR(30Ω)对启动时间和振荡裕度的影响,必要时调整反馈网络或采用外部起振增强措施。

七、质量与可靠性

雅晶鑫系列产品针对工业级应用设计,具有稳定的制程控制与测试流程,适合批量化生产与长期供货。建议在正式量产前与供应方确认样品一致性、出货检验项目与包装形式,以保证后续供货稳定与产品一致性。

如需样片评估、详细回流工艺参数或与特定振荡器芯片的匹配建议,可提供目标电路原理图以便给出更精确的方案。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
